Relationship among neonatal breast-feeding,body weight and blood volume of newborn heel

Objective To investigate the impact of the amount of breast-feeding and body weight on blood volume of newborn heel. Methods To divide the big children and low birth weight children into the first group and the breast-feeding and breast-feeding at less than the full amount of the newborn into the second group. On the condition of there was no difference in birth weight, birth time and breast-feeding time of the newborn to observe the relation between breast-feeding quantity and the rate of taking blood at the first time successfully. For birth time and breast-feeding time did not different significantly and were eating enough breast milk cases, to observe the relationship between body weight and the rate of taking blood at the first time successfully.Results The rate of taking blood at the first time successfully of those who had a sufficient amount of breast-feeding was significantly higher than that of those who didn't have enough amount of breast-feeding(P 0.05). Conclusions Newborn not only need to eat breast milk for 72 hours but also need to eat enough every time.This is the key to improve blood quality and protect the accuracy of screening results of neonatal diseases.
